In my opinion there is no specific frequency for metals, the phenomenon exists in a wide range from Khz to infrared. All that remains is to experiment and it is very important to have a field where to do the tests, it is necessary to bury the metals, for example gold / silver and wait at least a few months or less, it depends on the type of soil.
